Packaging blank



FIG. 1 is a front perspective view of a packaging blank showing our new design; and,

FIG. 2 is a side elevation view thereof.

The evenly spaced dashed lines represent fold lines and form part of the claimed design.

The dotted lines are for environmental purposes only and form no part of the claimed design.

The light weight shade lines are used to show that the surface is substantially planar and not to be interpreted as surface ornamentation. 

CLAIM The ornamental design for a packaging blank, as shown and described.
